Bottom Line: BAV was found in 19 patients (0.9 %), from which type 0 was diagnosed in five patients (0.2 %) and type 1 in 14 patients (0.7 %) - there was no patient with BAV type 2.QAV variant did not deteriorate AV function.Moreover, we noticed that QAV variant did not deteriorate AV function.

ABSTRACT

Background: Bicuspid aortic valve (BAV) is the most common congenital cardiac anomaly. Other aortic valve variants are rare but are associated with an increased incidence of various pathologies of the aortic valve (AV). The aim of this study was to assess the AV function in regard to its anatomical variants morphology in patients who underwent 64-slice coronary computed tomography angiography (CCTA) for suspected or known coronary artery disease.

Methods: The results of 64-detector retrospective ECG-gated CCTA of 2053 patients (mean age 58 years; 1265 males) were analyzed retrospectively by experienced cardiovascular radiologist. Coronary anatomy (with coronary artery dominance) and the extent of occlusion in the coronary arteries were assessed. Furthermore morphological and functional status of AV variants were analyzed. Among measured parameters were area at the level of AV annulus, orifice and tubular portion of the ascending aorta.

Results: The AV was visualized in all CCTA studies and the analysis of its morphology and function was done in all patients. BAV was found in 19 patients (0.9 %), from which type 0 was diagnosed in five patients (0.2 %) and type 1 in 14 patients (0.7 %) - there was no patient with BAV type 2. Unicuspid (UAV) and quadricuspid (QAV) variant were both observed each in one patient (0.05 %). In rest of the patients from the study group tricuspid AV variant was recognized. Function of AV variants was mostly affected in BAV0 and UAV. Among patients with BAV1 there were patients with normal and abnormal function of AV. QAV variant did not deteriorate AV function. There was no difference in coronary artery disease and dominancy between different anatomical variants of AV.

Conclusions: During CCTA different valve variants can be detected and detailed analysis of valvular function can be proceeded. Larger values of annulus area, wider diameters of ascending aorta and more stenotic profile were observed in BAV 0, BAV 1 and UAV. Among AV variants morphology and function was mostly affected in patients with BAV 0 and UAV variants, while subjects with BAV1 had normal or abnormal function of the AV. Moreover, we noticed that QAV variant did not deteriorate AV function.

Mentions: The aortic valve was clearly visualized in all coronary computed tomography angiography studies and the analysis of its morphology and function was possible in all patients from the study group. Bicuspid aortic valves were found in 19 patients (0,9 %), from which type 0 was diagnosed in five patients (0,2 %) and type 1 in 14 patients (0,7 %) - there was no patient with BAV type 2. Unicuspid and quadricuspid variant were both observed only in one patient (0,05 %). In rest of the patients from the study group tricuspid aortic valve variant was recognized. For the comparison of morphology and function of tricuspid aortic valve consecutive first 24 patients were selected. Examples of unicuspid, bicuspid, tricuspid and quadricuspid valves are presented in Figs. 2, 3, 4 and 5.Fig. 2
